boiler involves circulation of water by natural convention.

Explanation: According to the method of circulation of the water, boilers are classified. Natural circulation: If the circulation of water takes place due to the difference in density caused by the temperature of the water, then it is called a natural circulation boiler. Forced circulation: If the circulation water takes place with the help of an external pump, then it is called a forced

Study of circulation ratio for natural circulation in

The basic objective of the paper is to identify the desired circulation ratio for the natural circulation of water tube boilers in different operating conditions. This requires the basic study of heat flux and the mode of the boiling heat transfer, and the phenomenon like departure from nucleate boiling and tube overheating. The parameters, which need to be studied are heat flux, pressure
